Answer / isda

as most of ac equipments depend on the variable magnetic
flow which produced from the ac current and which in dc
will be steady

Answer / pravin bhoi

The ac eqmnt wrkng based on principle of alterntg flux or curnt whch is nt psble with dc so..

Answer / sumit karwa

any kind of purely resistive load can be supplied by ac as
well as dc source

Answer / sennapparajan

y not. use through inverter.

Answer / sennapparajan

well friend. both of them resistive load. if u have doubt
just check in prctically.

Answer / valentine

running a 230V lamp on a DC 110V will cause d lamp to burn dim...

dats a resistive load...

charge a 110V DC battery using a 230V AC suppy will cause the battery to swell up and explode ...

so use equipment as per rated voltage and type !!!

Answer / pranav

In Most of AC equipments we have Inductors and as we know if
we ll apply DC across it a very high magnitude of voltage
will appear accros the winding ,as in case of Transformers
if we ll apply dc voltage wingings will get burnt.....

Answer / sennapparajan

@karwa...


Ya u r. right

Answer / deepak mishra

we can use pure resistive circuit to both ac and dc supply
but in case of induction type instrument we cant use dc bcz
induction principle is applicable to only ac. example are
induction motor and transformer

Answer / sennapparajan

what ever. only source is diffrent but...1230v dc supply is
smae only. did u check bult ac bulf with dc supply??

If a ACB breaker is tripping and closing problem, then what will we check internal..?

3 Answers  

when an induction motor runs on load.at that time if we reduce the supply voltage the current increases.But when it runs without load,if we reduce the supply voltage the current also reduced.why?.i checked it practically also.
